ABSTRACT

Objectives

Decline in language and cognitive functioning often deprives people living with moderate-to-severe dementia of self-reporting their quality of life (QoL) on the written and verbal formats of questionnaires. This systematic review aimed to evaluate the effectiveness of pictorial tools as an alternative method for enabling people living with dementia to self-report their QoL.

Methods

PubMed, PsycINFO, CINAHL, and EMBASE were searched. Primary research studies reporting on information elicitation from people living with dementia through pictures were deemed eligible. Six studies satisfied the inclusion criteria. Methodological quality of the studies was evaluated through Downs and Black checklist. Data was extracted according to population, intervention, comparator, and outcomes (PICO) and results were summarized and supplemented by narrative synthesis.

Results

Compared to usual communication methods, pictorial tools were found to have a superior effect on comprehension of conversations and decision-making abilities, minimal effect on preference consistency, and an undeterminable effect on discourse features.

Conclusions

There is consistent evidence that pictures enhance comprehension and might facilitate decision-making abilities.

Clinical Implications

QoL information can be elicited more effectively through pictorial tools. Future studies warrant development of pictorial versions of standardized QoL tools which will assist the inclusion of people living with severe dementia.

图片在从痴呆症患者那里获取信息方面有多有效？系统回顾

摘要

目标

语言和认知功能的下降常常使中度至重度痴呆症患者无法通过书面和口头形式的问卷自我报告他们的生活质量 (QoL)。这项系统评价旨在评估图形工具作为痴呆症患者自我报告生活质量的替代方法的有效性。

方法

检索了 PubMed、PsycINFO、CINAHL 和 EMBASE。报告通过图片从痴呆症患者那里获取信息的初步研究被认为是合格的。六项研究满足纳入标准。研究的方法学质量通过唐斯和布莱克清单进行评估。根据人群、干预、比较和结果（PICO）提取数据，并通过叙述综合对结果进行总结和补充。

结果

与通常的交流方法相比，图像工具对对话理解和决策能力具有优越的效果，对偏好一致性的影响最小，对话语特征的影响不可确定。

结论

有一致的证据表明图片可以增强理解力并可能促进决策能力。

临床意义

通过图形工具可以更有效地获取生活质量信息。未来的研究需要开发标准化生活质量工具的图形版本，这将有助于将患有严重痴呆症的人纳入其中。
